Negative thought: Mechanical! You flat on the Queen K and frustratingly watch your competitors fly by as you count every minute you lose.

Combat it: “If you haven’t thought through these scenarios, they can be very troubling on race day,” Winsberg says. “This is a tough one because we don’t get mechanicals often. Stay focused on what you can control—not about how much time you have lost, or who is going by you. Focus on fixing it and then get back into race mode by bringing your mind back to your body. Focus on breathing, relaxing your shoulders, smooth pedal stokes, steady power.”
